HDT-201 HDR-201

OFDM Modulation enabled use at the frequency band  where much noise exists. image:HDT-201 HDR-201

The HDT-201 and the HDR-201 are a transmitter and a receiver for live HD/SD broadcasting with coaxial / optical fiber cable network.The compact body and easy operation facilitates on-site work greatly!

Major Features

  • Compact and light-weight body of the transmitter realized excellent mobility.
  • H.264 encoder and decoder are integrated in each compact body,facilitating on-site setup.
  • Noiseless digital intercom greatly helps communications between the cite and the center (head-end).
  • Bit rates can be programmed in the range from 5 to 22Mbps, acquiring beautiful images.
  • The V-mount batteries can be used as power source of the transmitter, which needs no power generators on the site.
  • IP transmission function ; The devices can be used even where no coaxial cable lines are available.
